New study shows how salmonella tricks gut defenses to cause infection
A study led by UC Davis distinguished professor Andreas Bäumler uncovered how Salmonella, a major cause of food poisoning, can invade the gut despite the presence of protective bacteria.
Gut bioelectricity provides a path for bad bacteria to cause diseases
UC Davis Health researchers has discovered a novel bioelectrical mechanism pathogens like Salmonella use to find entry points in the gut lining that would allow them to pass and cause infection.
Surprise Finding in Study of Environmental Bacteria Could Advance Search for Better Antibiotics
In what they labeled a “surprising” finding, Johns Hopkins Medicine researchers studying bacteria from freshwater lakes and soil say they have determined a protein’s essential role in maintaining the germ’s shape.
Most Salmonella illnesses from chicken caused by few products with high levels of virulent strains
Raw poultry is one of the main causes of Salmonella poisoning, which affects thousands of people in the U.S. every year. A new study from the University of Illinois Urbana-Champaign shows that few products with high levels of very virulent Salmonella strains are responsible for most of the illnesses from raw chicken parts.
Opportunistic Colonizers: Selectively Targeting Tumor Cells with Bacteria
Live bacteria can be applied in cancer therapy given their ability to deplete nutrients and induce cell death in tumors. However, the interaction between bacteria and tumor cells is risky and can exacerbate the inflammatory response and the expression of anti-apoptotic genes.
Salmonella Outbreak Linked to Cucumbers
The Centers for Disease Control and Prevention is warning of a salmonella outbreak linked to cucumbers. More than 160 people across 25 states and Washington, D.C. have reported illnesses. According to the CDC, 54 people have been hospitalized. The possible…
Study identifies increase in antibiotic-resistant typhoid
Ciprofloxacin is the first-line drug for treating typhoid fever in many countries in Africa with a high disease burden, but the emergence of non-susceptibility poses a challenge to public health programmes.
Protect Yourself Against Salmonella
David Winter, MD, at Baylor Scott & White Health, says proper hygiene is key to fighting against salmonella. What You Need to Know: Salmonella can cause severe diarrhea. Get a diagnosis first before treating salmonella. Salmonella symptoms include fever and…
Tomato juice’s antimicrobial properties can kill salmonella
Tomato juice can kill Salmonella Typhi and other bacteria that can harm people’s digestive and urinary tract health, according to research published this week in Microbiology Spectrum, a journal of the American Society for Microbiology.
Researchers create packaging tray that warns of contamination before food is unwrapped
Researchers at McMaster University have created a new packaging tray that can signal when Salmonella or other dangerous pathogens are present in packages of raw or cooked food such as chicken.
New technique for detecting foodborne illness early
University of Delaware researchers have developed a new technique to catch bacteria in the act, detecting it on produce before it reaches stores, restaurants and consumers’ plates. The new platform can detect foodborne pathogens in three to six hours.
Salmonella Solution
McMaster University researchers have developed a rapid and inexpensive test for Salmonella contamination in chicken and other food – one that’s easier to use than a home COVID test.
Salmonella exposure a risk for colon cancer
Researchers studied human colon cancer tissue samples and animal models and found that exposure to salmonella was linked with colon cancers that developed earlier and grew larger.
Low levels of high-risk salmonella evade traditional methods of detection
Poultry is responsible for more than one out of every five cases of salmonella infection in the U.S. But traditional methods of testing the chicken you grab off the grocery shelf may not be enough to detect all strains of the bacteria, according to new research from the University of Georgia.
‘Friendly’ gut bacteria may eliminate pathogens by competing for energy resources
New research from scientists at UC Davis Health provides clues for how friendly bacteria in the gut — probiotics — may help eradicate bacterial pathogens like Salmonella by being able to compete with them for needed resources.
Food Safety in Focus: Clarifying Potential Hazards on Low-Moisture Foods
IAFNS supports studies on threats posed by pathogens and viruses in low-moisture fruits and nuts.
Can you get salmonella from your backyard chickens?
For those with backyard poultry, like chickens or ducks, a Texas A&M AgriLife expert encourages taking precautions against salmonella exposure as cases spike across the U.S.
A new method may make tomatoes safer to eat
When vegetable farmers harvest crops, they often rely on postharvest washing to reduce any foodborne pathogens, but a new University of Georgia study shows promise in reducing these pathogens – as well as lowering labor costs— by applying sanitizers to produce while it is still in the fields.
USDA Says Current Poultry Food Safety Guidelines Do Not Stop Salmonella Outbreaks
Current poultry food safety guidelines for Salmonella, the leading cause of foodborne illness outbreaks, are inadequate. A new study conducted by Thomas Oscar, USDA Agricultural Research Service, “Salmonella prevalence alone is not a good indicator of poultry food safety,” published in Risk Analysis, explores additional factors that must be considered in order to identify poultry products that are truly safe for human consumption.
Sneaky salmonella finds a backdoor into plants
Researchers have discovered that bacteria such as salmonella and E.coli have a backdoor to capitalize on our reliance on leafy greens for a healthy diet. Wild strains of salmonella are delivering foodborne illnesses by circumventing a plant’s immune defense system to get into the leaves of lettuce.
Reusing chicken litter shows benefits
Beneficial bacteria in reused poultry litter can reduce Salmonella levels
Researchers find one-two punch may help fight against Salmonella
Researchers found that co-administering dephostatin and colistin in mice with a lethal Salmonella infection significantly prolonged animal survival and used a lower concentration of colistin than is normally required for treatment, thereby reducing its toxic effect.
Food scientists slice time off salmonella identification process
Researchers from Cornell and the Mars Global Food Safety Center can complete whole-genome sequencing to determine salmonella serotypes in two hours and the whole identification process within eight hours.
MORE THAN A WATCHDOG
Study in mice shows the nervous system not only detects the presence of Salmonella in the gut but actively stops the organism from infecting the body
Nerves in the gut prevent Salmonella infection by shutting the cellular gates that allow bacteria to invade the intestine and spread beyond it
As a second line of defense, gut neurons help avert Salmonella invasion by maintaining the levels of key protective microbes in the gut
Findings reveal prominent role for nervous system in infection protection and regulation of immunity
